Hello all,... as things are somewhat slow in my industry right now....i offer up my sewing and pull testing facilites for anyone wishing to see a specific item tested. If you have items you want pull tested you can send them to me...or if you have a specific piece of sewn gear you would like to see built and busted, i can do this too.

If i hadn't glanced thru all the "happenings" of the last year on this board, i wouldn't have had a clue what your tallking about. But i did... and so i must respond; "no" sorry Moose Droppings, i don't think i can pull all that stuff from the abiss....besides i dont think my load cell would know what to do with it! Funny though!

I don't purport to have the knowledge that some of the individuals have on here, thats for sure..... but i do have equipment, supplies and willingness to help.

I love to see the results from pull tests -- reminds me of days in the engineering lab.

I would love to see a pull test of a quad as described in JL's anchor book. Basically a 4 stranded equalette. I make mine out of 8mm nylon cord with a double fisherman's knot and then overhand knots about 12 inches apart as limiting knots. I am really curious to see where the failure point in this would be.

Sweet. Here is a clarification of the quad test: If I'm setting a quad at a two bolt anchor I normally clip the rope-side biners into three of the four strands between the limiter knots. I'm guessing that it will break at one of the knots.

ok.... first let me get some coffe in my blood stream (just woke up)..... then i'll have to get my head around your anchor setup. I use to be a dirt bag, yosemite, squamish, climbing fool. But now im just a fool that hasn't climbed in years; you know, got hitched, got animals, got a belly.....then i discovered paragliding and that pretty much put a nail in climbing's coffin. Once my poor old shop dog (he has cancer now) passes on, i may get back up to squamish....

I realize that the test might not be super real world since the the angle between the two legs will be greater in a two bolt belay but I can back calculate the strength for a given geometry once I know the breaking strength when there is no angle.

ok...yup....thats the image i found too.... So rigging that of my anchor plate, given the shallowness of the angles is ok......ok. I may have a solution to rig to a wider angle.... i guess somewhere in the area of 45 degress would be nice if possible eh?

OK....So like this?.... I see in the other pic you showed me that the fellow grabbed two strands seperatley with each rope side biner. As you can see,...that would be the rigging plate i would use to make life easy for me to rig at the anchor end of my test bed. I do have an "ariel" spreader bar for "performers"...but im not sure i want to risk it on this test.

Also the cord in these pics is 6mm. Its what i had at home (where my pull tester is). I thought i would do a prelim test pull with that.... or would you prefer 8mm straight up?... I'll have to go buy some=reason to go look at goodies at the climbing shop....so no worries.Im thinking with 6mm the break could be over the bolt carabiners given smaller radius than 8mm setup?

Also...what about biner selection at the pins and at the rope end? probably doesn't matter.

Let me know.... I may just go do this test now before the coffee wears off

ps how do i get the images to self view in the message rather than just sit as atachments
